The leaves on this are pretty large. Found it about 1 mile from my house in a field of cotton.. Can you believe I spotted it from the Hiwy..?? The flowers looked dark blue/purple when I saw it at about 11:00 AM and I pulled out three plants at 4:00 PM and all the flowers were closed, and have them soaking in superthrive/water.. they perked right up. There is even a bud on it, so hopefully it will bloom in the morning.
